“…Studies have demonstrated that compared to traditional biomarkers, metabolic enzymes are superior as predictive biomarkers for various cancers (Dong et al, 2015;Xu et al, 2021). Metabolic alteration has wideranging effects, such as angiogenesis, metastasis, and immune escape, which has provided opportunities to solve immunotherapy resistance and poor clinical outcomes (Broadfield et al, 2021;Jones et al, 2021;Zanotelli et al, 2021). To date, the expression patterns of metabolic enzymes have been widely studied in different cancer types, such as liver, gastric, colorectal, breast, and prostate cancer (Lavorgna et al, 2018;Zinger et al, 2019;Rivello et al, 2020;Sun et al, 2020;Xu et al, 2020;Jiang et al, 2021).…”
